I’ve never seen it done that way but I would say it’s 32 / 4 = 8

Collectively, there are 32 squares, separated into groups of 4. When you divide 32 by 4, you’re left with 8 which is reflected by the 8 blue ovals

A ball is dropped from a height of 30 feet and each time it hits the ground it bounces 0.75 of the previous height. What is the
QveST [7]
If the ball is "starting" at 30 feet, then to get how high it went the bounce, we simply multiply 0.75 times 30, and to get the next bounce's height, is again (30*0.75)0.75, and so on.

so... the 0.75 or 3/4 is our "multiplier" to get the next term's value, or our "common ratio".  So is just a geometric sequence, if the first term is 30, the common ratio is 0.75, what's the 4th term?  Because the first bounce happens after the 30 feet, at the 2nd term, thus the 4th term is the 3rd bounce.

\bf n^{th}\textit{ term of a geometric sequence}\\\\
a_n=a_1\cdot r^{n-1}\qquad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term's value}\\
r=\textit{common ratio}\\
----------\\
a_1=30\\
r=0.75\\
n=4
\end{cases}
\\\\\\
a_4=30\cdot (0.75)^{4-1}\implies a_4=30(0.75)^3

if the population of a country increases at a rate of 1.5% annually, and it’s current population is 430,000, how many years will
aleksandrvk [35]
Hi,
a_0=430000\\
a_1=a_0*1.15\\
a_2=a_1*1.15=a_0*1.15^2\\
...\\
a_n=a_0*1.15^n\\

a_n \geq 3*a_0\\

1.15^n \geq 3\\

n*ln(1.15) \geq ln(3)\\

n \geq  \dfrac{ln(3)}{ln(1.15)} \\

n \geq 7.86059688...\\\\

\boxed{n \geq 8}\\
